Unrine Infiection

Asked for Male, 25 Years

I had a urine infection 2/3 years ago. At that time urine tests indicated a count of 20-22 Red blood cells in the urine sample.
Latest tests also indicate a count of 10 - 12 RBC. What coud be the reson for this especially for such a prolonged period(2-3 years). Is it somethibg serious?
